Project Description

Summary:  View help for Summary Here is the data used in the paper titled "Does democracy cause innovation? An empirical study of the Popper Hypothesis". Democratic countries produce higher levels of innovation than autocratic ones, but does democratization itself lead to innovation growth either in the short or in the long run? The existing literature has extensively examined the relationship between democracy and growth, but seldom explored the effect of democracy on innovation, which might be an important channel through which democracy contributes to economic growth. This article aims to fill this gap and contributes to the long-standing debate on the relationship between democracy and innovation by offering empirical evidence based on a dataset covering 156 countries between the year 1964 and 2010. The results from difference-in-difference method show that democracy itself has no direct positive effect on innovation measured with patent counts, patent citations and patent originality.
